This video introduces how to calculate motor speed RPM Rev/s or Rev/min by using the encoder raw data. The encoder value is counted by Siemens S7-1200 PLC HSC(High-Speed Counter).

According the link "RPM Equation" as the link the below as well as the recommendation from viewer 'Vu duy phuong", the equation used in the video:
Speed (RPS) = [(C1-C2) / 0.2s ] / 1024
or (RPM) = [(C1-C2) / 0.2s ] *60/ 1024
Here the interval time between C1 and C2 is 0.2s (200ms interrupt OB)
